Delta Air Lines struggled for a fourth straight day to recover from a worldwide technology outage caused by a faulty software update, stranding tens of thousands of passengers and drawing unwanted attention from the federal government.
The airline’s chief executive said it would take “another couple days” before “the worst is clearly behind us.” Delta’s chief information officer said Monday that the airline was still trying to fix a vital crew-scheduling program.
Other carriers were returning to nearly normal levels of service disruptions, intensifying the glare on Delta’s relatively weaker response to the outage that hit airlines, hospitals and businesses around the world.
Transportation Secretary Pete Buttigieg spoke to Delta CEO Ed Bastian on Sunday about the airline’s high number of cancellations since Friday. Buttigieg said his agency had received “hundreds of complaints” about Delta, and he expects the airline to provide hotels and meals for travelers who are delayed and to issue quick refunds to customers who don’t want to be rebooked on a later flight.
“No one should be stranded at an airport overnight or stuck on hold for hours waiting to talk to a customer service agent,” Buttigieg said. He vowed to help Delta passengers by enforcing air-travel consumer-protection rules.
